Description
Summary:The performance of an adaptive interference canceller (AIC) is sensitive to the dasiasignal crosstalkpsila in the reference channel. This paper analyzes the performance of the crosstalk-resistant AIC at first. The transmitting function of the channel of the signal crosstalk in the cosite interference can be estimated approximately, so an additive channel is added at the input of the reference signal to suppress crosstalk components in its reference channel. This method can reduce the SIR in the reference channel and result in the increase the SIR of the AIC at the output. Computer simulations demonstrate that the proposed algorithm can get a high performance and has better practicability.
